What if hibernating animals of different species formed an orchestra and performed a symphony about their winter’s sleep? Well, they did—sort of.

Because this is the science version of "Peter and the Wolf"... A flute playing wood frog who freezes. A bassoon blowing painted turtle who (ahem) breathes through its butt. A trumpet blasting common poorwill who falls asleep anywhere, anytime. A harp plucking mosquito who goes into a sci-fi suspended animation. A drum thumping black bear who stays fat all winter long. And, of course, a theremin tuning Antarctic cod who goes semi-comatose in the dark.

Ladies and gentlemen, "The Sleep Cycle" by L’orchestre D’hibernation Animaux.

What do you see when you picture a nautilus? On the surface, it's a beautifully strange shelled cephalopod. But look closer... Our story starts with Act 1, an ode to the nautilus' 500 million year old brain, nose, and its tentacle like cirri. Because the nautilus doesn't need to see. After all, it experiences the world by smelling and feeling it. Act 2 looks inside the nautilus' shell and finds the cephalopod has something in common with Star Trek II: The Wrath of Khan and disease research. Finally, in Act 3, Captain Nemo's Nautilus ship leads to Popular Science's true blue discovery of the lost first underwater film. It's a story too strange and horrifying to be fiction (and, yes, it involves a dead horse floating upside-down in the ocean).

The *Experimentals video series features three science stories on an always curiously interpreted theme. And it’s made as if it's an 80s educational TV show you half remember.

This is what the universe looks like after 146 years of Popular Science—a video timeline of weird, wild, and wondrous moments in science history. And it’s all animated with 146 years of PopSci covers, photos, and illustrations.

Season after season, extreme weather bombards the continental United States. Over the next 83 years, its cascading effects will force U.S. residents inward, upward, and away from newly uninhabitable areas. But don’t worry: here's a map of how these factors will alter the country’s landscape in 2100.

Dear viewers: The extinct Tasmanian tiger of Australia is still extinct, yet, there’ve been a string of “plausible” sightings of the long gone marsupial. Here's how you can be prepared should you ever encounter an extinct beast.
